For the system of Problem P10.20, design a phase lag network to yield the desired specifications, with the exception that a bandwidth equal to or greater than 2 rad/s will be acceptable.
Problem:
An uncompensated control system with unity feedback has a plant transfer function
We want to have a velocity error constant of Kv - 20. We also want to have a phase margin of approximately 45° and a closed-loop bandwidth greater than ω= 4 rad/s. Use two identical cascaded phase-lead networks to compensate the system.
